Three Mustangs sit in dappled shade behind the Gothic-arched gate of the Edsel & Eleanor Ford House. The 1964.5 convertible in Wimbledon White is VIN 001, the first production Mustang built. In blue is another convertible, the first Mustang sold in America, to then-22-year-old Gail Wise, an elementary school teacher outside of Chicago. And last, built in homage to VIN 001, is the 10-millionth Mustang built—another Wimbledon White convertible. Leaves flutter down from the trees through the space that separate the cars, but it’s 54 years of pony car history between the trio that hangs, invisible, in the air between them.
